          """
          Gets a list of Deployment Servers based on optional sorting and filtering, and constrained by start and count
          parameters.
  
          Args:
              start:
                  The first item to return, using 0-based indexing.
                  If not specified, the default is 0 - start with the first available item.
              count:
                  The number of resources to return. A count of -1 requests all items.
                  The actual number of items in the response might differ from the requested
                  count if the sum of start and count exceeds the total number of items.
              filter (list or str):
                  A general filter/query string to narrow the list of items returned. The
                  default is no filter; all resources are returned.
              fields:
                  Specifies which fields should be returned in the result set.
              query:
                   A general query string to narrow the list of resources returned. The default
                   is no query - all resources are returned.
              sort:
                  The sort order of the returned data set. By default, the sort order is based
                  on create time with the oldest entry first.
              view:
                  Return a specific subset of the attributes of the resource or collection, by
                  specifying the name of a predefined view. The default view is expand - show all
                  attributes of the resource and all elements of collections of resources.
  
          Returns:
               list: Os Deployment Servers
